Bluetooth®LE
Introduced in Bluetooth version 4.0, Bluetooth LE is a significant foundation for IoT applications. Unlike Bluetooth Classic, Bluetooth LE is more prominent in applications where power consumption is crucial and where small amounts of data are transferred infrequently. Telink's market-proven Bluetooth LE SoCs and SDKs have been powering hundreds of millions of IoT devices since 2014.
TLSR825x Series
The TLSR825x series offers ultra - low - power, concurrent multi - protocol iot solutions within the ISM 2.4GHz band. This family provides support for the entire range of Bluetooth Low power, Bluetooth Mesh, Zigbee, RF4CE, and 2.4GHz proprietary protocols.
